Periodical check-ups
≥To maintain the highest image quality, we 
recommend replacing worn parts such as heads 
after approx. 1000 hours of use. (This, however, 
depends on operating conditions including 
temperature, humidity and dust.) 
Explanation of terms

Automatic white balance
White balance adjustment recognizes the colour 
of light and adjusts so the white colour will 
become a pure white. The movie camera 
determines the hue of light that comes through 
the lens and white balance sensor, thereby 
judging the recording condition, and selects the 
closest hue setting. This is called automatic white 
balance adjustment. However, since the movie 
camera only stores white colour information 
under several light sources, automatic white 
balance adjustment does not function normally 
under the other light sources. 
Outside of the effective range of automatic white 
balance adjustment, the image will become 
reddish or bluish. Even within the effective range 
of automatic white balance adjustment, the 
automatic white balance adjustment may not 
function properly if there is more than one light 
source. For light outside the functional auto white 
balance adjustment range, use the manual white 
balance adjustment mode.

White balance
The image recorded by the movie camera may 
become bluish or reddish under the influence of 
light sources. To avoid such phenomena, adjust 
the white balance.
White balance adjustment determines the white 
colour under different light sources. By 
recognizing which is the white colour under 
sunlight and which is the white colour under a 
fluorescent lamp, the movie camera can adjust 
the balance among the other colours.
Since white colour is the reference of all colours 
(light), the movie camera can record pictures in a 
natural hue if it can recognize the reference white 
colour. 
Extremely high precision technology is 
employed to produce the LCD monitor 
screen featuring a total of approximately 
113,000 pixels. The result is more than 
99.99% effective pixels with a mere 0.01% of 
the pixels inactive or always lit. However, 
this is not a malfunction and does not affect 
the recorded picture.
